The red wood ant is a large forest ant that builds big, dome-shaped nests of twigs, grass and pine needles. It lives across much of Europe and northern Asia, from Scandinavia and Great Britain to Lake Baikal. It is special because its colonies can be huge and have several queens, and it can spray formic acid from its abdomen to defend itself.1

Jinsi ya kumtambua

  • Head and thorax (front body) are red, while the abdomen (rear) is brownish-black.1
  • Usually has dark patches on the head and the upper part of the thorax, though some individuals are more uniformly reddish.1
  • Workers measure 4.5 to 9 mm long and have large mandibles (jaws).1
  • Builds large, conspicuous dome-shaped mounds in woodland clearings.1

Mara nyingi huchanganywa na: Closely related wood ants are hard to separate by eye. Under magnification, the amount of hair is a key clue: this species is hairier than Formica polyctena but less hairy than Formica lugubris.1

Ana hatari gani kwa watu?

Hufanya nini akiogopa?

When threatened, workers spray formic acid from their abdomens and defend the nest by guarding entrances and patrolling nearby areas.1

Akikunyunyizia

  • Osha na upoze sehemu zilizodungwa.
  • Mtu akipata shida ya kupumua, uso au koo likivimba, au akijisikia kuzimia, hiyo ni dharura ya mzio: piga namba ya dharura.

Daima piga namba ya dharura kwanza (112, 000, 911). Huu ni mwongozo wa jumla wa huduma ya kwanza, si ushauri wa kitabibu. Misingi ya huduma ya kwanza

Kaa salama

  • Kamwe usimguse, kumkamata wala kumchokoza mnyama wa porini, hata akiwa mdogo, na hata akionekana amelala au amekufa.
  • Mpe nafasi. Ukikutana naye, tulia, rudi nyuma polepole na umwache aende zake.
  • Akikunyunyizia: tulia, usitikisike, piga namba yako ya dharura (112, 000, 911) au nenda hospitali haraka. Kumbuka alivyoonekana, picha husaidia.

Hakuwindi wewe. Hutumia sumu yake kukamata chakula au kujilinda, na hupendelea zaidi kujificha. Zaidi kuhusu kukaa salama

Ukweli

1

Formic acid was first extracted in 1671 by the English naturalist John Ray, who distilled a large number of crushed ants of this species.1

2

Wood ants raid the nests of other ants and insects, and some species take captured young back to their own colony as workers.1

3

Some colonies are huge networks of connected nests, and some of these nests can be several metres high and wide.1

4

Wood ants collect resin from conifer trees and use it in their nests for structure, protection and antimicrobial defence.1

5

A large colony may have 100,000 to 400,000 workers and 100 queens.1

6

Forestry uses this species, which is introduced into an area as a form of pest management.1
